ATF 4401

ATF 4401 is an automatic transmission fluid that meets the JASO ATF 4401 standard and is recommended for many Suzuki models with automatic gearboxes. It provides stable viscosity over a wide temperature range, protects gears from wear, and prevents overheating under high loads. When selecting a lubricant with the “SUZUKI” specification, be sure that it is specifically ATF 4401, as other types (e.g., Dexron III or Mercon) may not meet compatibility requirements and could reduce transmission life. Using original or JASO ATF 4401‑certified fluid guarantees optimal gearbox operation and extends the vehicle’s service life.
